I have a 2011 nissan frontier 4.0 with a automatic transmission. I do not do any towing with this truck. When should I change the fluid? And should I have the fluid change or the transmission flushed?
What is your question?
The nissian dealers want to flush my system when im being told by other mechanics just to change the fluid. whats the best method?
RepairPal Certified shops can diagnose and repair your 2011 Nissan Frontier. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Regular service > drain fluid - replace filter - refill with proper fluid.
Best not to flush a transmission which has several miles on it - it can result In particulates being transferred into critical transmission fluid passages.
I personally do not recommend it .... However 'some' do - they usually have the flush machine to pay for as well ..!
